12.09.2024: Sessions 💬

Available in Phoenix 7.0+

Sessions allow you to group multiple responses into a single thread. Each response is still captured as a single trace, but each trace is linked together and presented in a combined view.

Sessions make it easier to visual multi-turn exchanges with your chatbot or agent Sessions launches with Python and TS/JS support. For more on sessions, check out a walkthrough video and the docs.
